What am i doing wrong here

Ok i tried to follow some looped background example.Try this

fileconvoy.com/dfl.php

I see a white gaps,what could be the reason

I seem to remember this was a problem with Pixel Rounding or rather that the backgrounds got rendered a subpixel apart from eachother or something.

I'm at work now and I'll try to find a solution to it later, but if it's not too ugly you can just overlap the backgrounds by half a pixel or something.

I tried overlapping but that didn't help.

Thanks anyways!!!

HAHA finally overlapping helped
